EONON Bluetooth OBD2 Diagnostic Adapter for Android Stereos — V0056, Live PIDs & Code Reader

The Eonon V0056 is a Bluetooth OBD2 adapter that connects to EONON Android head units so you can read engine diagnostics and live sensor data on your car stereo.

Plug-and-play and designed for in-dash Android radios, the V0056 turns your compatible EONON head unit into a vehicle diagnostics display. It communicates over Bluetooth with apps such as Torque to show fault codes, sensor readings and real-time parameters. The adapter reads both generic and maker-specific trouble codes and draws from a database of over 3,000 code definitions, making it a helpful companion for basic troubleshooting, monitoring, and performance checks.

How do I use the V0056 with my EONON Android stereo?

Getting started requires three quick steps: plug the V0056 into the vehicle’s OBD2 port, pair it with your EONON head unit via Bluetooth, and open a compatible app (Torque recommended). The adapter is bus-powered and begins transmitting live OBD data immediately after pairing. No complex installation or tools are needed.

• Plug into the car’s standard OBD2 socket (usually under the dash).
• Pair Bluetooth from the EONON stereo settings.
• Launch Torque or another OBD2 app to view codes and gauges.

What vehicle data and fault codes can this scanner read?

The V0056 covers common OBD-II parameters including engine RPM, coolant temperature, vehicle speed, and fuel trims, plus many additional sensors. It can pull generic and manufacturer-specific diagnostic trouble codes and display definitions from its built-in code library. This gives you a clearer idea of what a reported fault means before deciding next steps.

• Live PIDs: RPM, speed, coolant/air temps, MAP, MAF and throttle position.
• Fuel system status and short/long-term fuel trims for tuning insight.
• Read and clear stored and pending fault codes with definitions.

Which vehicles and apps are compatible with V0056?

The adapter follows the OBD-II standard and works with EONON Android head units and most vehicles built to OBD-II specifications (generally post-1996 in the U.S.). Compatibility depends on the vehicle’s supported OBD protocols and the app you choose. For best results, install the Torque app from Google Play on your EONON stereo before connecting.

• Compatible with EONON Android stereos and most OBD-II vehicles.
• Works with Torque and many third-party OBD apps that support Bluetooth adapters.
• No compatibility with non-OBD-II or some manufacturer-locked systems.

How reliable and supported is the V0056 adapter?

Eonon supplies an 18-month warranty and a 30-day money-back guarantee for customer confidence. The adapter uses standard OBD-II communication, so reliability depends on vehicle wiring and app stability. If you need help, Eonon’s customer support can assist with pairing, app setup, and diagnostics basics.

• 30-day return window and 18-month warranty for quality issues.
• Standard Bluetooth connection—no batteries or charging necessary.
• Customer service available through the seller contact on the product page.

Who this is for: The Eonon V0056 is aimed at drivers and DIYers who want immediate access to engine data directly on an EONON Android head unit—useful for monitoring performance, confirming fault codes before a shop visit, or creating custom dashboards with the Torque app. It’s not a professional shop tool, but it’s an affordable, user-friendly option for routine checks, troubleshooting, and live data monitoring in OBD-II equipped vehicles.
